Population profiles, or population pyramids, depict a nations population in terms of age and gender. It can be thought of as two histograms put back to back and with it one can see how old or young a nations population is. This is the population pyramid for Spain in 2003. The largest age range was in their thirties. It can also be noted that the population is fairly even between men and women, except in the 80+ range women out live the men.
